It is an offence in law for a driver to pick up or set down passengers in restricted zones. However, for the convenience of people with disabilities, the police have agreed to exercise discretion to allow drivers of taxi, private car, private light bus and private bus to pick up or set down passengers with disabilities in restricted zones (except expressways and 24 hours restricted zones), provided that no hazard or major disruption is caused to other road users. As evidence of the journey, passengers with disabilities can issue a completed “Certificate for Picking Up or Setting Down of Passengers with Disabilities in Restricted Zones” to the driver, with information on the journey (date, time and pick up/set down place) and vehicle registration number (see Figure 4). Passenger with visual impairment can fill in the certificate in Braille. In the event that the driver is interrogated by a police officer, he can show the certificate to the latter for consideration.
